Short description

Artificial animal evolutionary simulation. Evolve your own AI robots in a simulation of nature!

About this game

EVOLVE YOUR OWN AI ROBOT! You are The (zoo)Keeper overseeing a population of evolving AI robots in a dynamic voxel landscape. These robotic animats walk, jump, eat, mate, fight, and adapt to their surroundings as they strive to survive and reproduce. In theory, the capacity for their intelligence is limitless, as their brains can evolve to any shape and complexity. Will you choose to passively observe their evolution, letting nature take its course? Or will you intervene, shaping their world and influencing their evolutionary path? Design your own animal robots, build custom terrains, manipulate the environment, interact with the animals, and watch as each generation learns, adapts, and competes in a simulated ecosystem that’s as unpredictable as nature itself. The fate of their evolution is in your hands. --------- Introducing a new god game and evolutionary simulation, where you evolve the brains of artificial animals to make them more intelligent, to better achieve survival and reproduction. The animals are real AI robots running directly on your computer. They are controlled by classic neural networks and other types of AI such as non-axiomatic reasoning system. They have a simple form of vision sense, touch sensation, and internal sensations, and they can move each individual body segment. They can eat, mate, and fight, all while learning and evolving in a sandbox voxel environment. Watch evolution passively, or enjoy various interactive features including: Voxel World : place voxels and modify the environment with sand, stone, water, and more. Impact Evolution using your Research Journal: modify mutation rates in your Research Journal -- higher rates means faster but more unstable evolution, lower rates means slower but more stable evolution. Pick up animats : Pick up animats and move the animats around with left click. Build your own Robot: Go to the Animat Creator from the main menu to create your own robot. You can save it and load it into a simulation to evolve its brain!

Steam marketplace comparison data

Price History Overview

USD uses SteamPulse's own locally recorded daily store snapshots, so this overview reflects the exact regional price history that SteamPulse has captured for this currency.

Coverage And Tracking Window

  • Snapshots: 1
  • Coverage: Oct 6, 2026 to Oct 6, 2026
  • Lowest observed: $4.99
  • Highest observed: $4.99

ERAIASON's USD price history spans from Oct 6, 2026 to Oct 6, 2026, with 1 recorded snapshot across 1 calendar day. Each row records the available final price, listed base price, and discount metadata for that observation. Within this coverage the lowest recorded price is $4.99, the highest is $4.99, and the first visible tracked price is $4.99. These comparisons apply only to the snapshots SteamPulse holds; missing observations can contain changes that are not represented here.

For USD, SteamPulse uses locally captured regional storefront snapshots and does not reconstruct older prices with exchange-rate conversion. The chart and table show the values recorded for this exact currency from the stated coverage start. Additional snapshots extend that record, but they do not fill unobserved days or prove what the storefront displayed between observations.

Discount Windows And Sale Timing

  • Discount windows: 0
  • Discounted days: 0 days
  • Deepest markdown: No discount tracked
  • Latest sale window: No sale window tracked

ERAIASON's tracked USD rows do not contain a discount window. This means no available snapshot in the stated coverage has usable discount metadata; it does not prove that the game was never discounted. Missing snapshots or archived rows without complete metadata can hide a sale, so SteamPulse does not infer pricing strategy from this absence.

If a later snapshot includes discount metadata, it will appear here with its recorded depth, price, date, and sale name when available. Until then, this section should be read only as a description of the available rows, not as evidence about the publisher's promotion policy.

Observed Price Changes And Stable Runs

  • Observed price drops: 0
  • Observed price rises: 0
  • Longest stable run: 1 day of uninterrupted daily tracking
  • Current run: 1 day of uninterrupted daily tracking

Outside rows carrying discount metadata, the tracked price has not recorded a separate price rise or drop yet. That means the observed undiscounted level has stayed stable across the snapshots SteamPulse currently holds. This is a statement about the recorded coverage only; it does not prove that an older or missing price change never happened.

The longest unchanged price stretch in the current record lasts 1 day of uninterrupted daily tracking at $4.99, from Oct 6, 2026 through Oct 6, 2026. Among rows without discount metadata, the longest unchanged run lasts 1 day of uninterrupted daily tracking at $4.99. The latest run records $4.99 for 1 day of uninterrupted daily tracking as the same recorded undiscounted price. Run lengths describe consecutive stored observations only and do not establish that a price is permanent.

Latest Snapshot And Sales Context

  • Current price: $4.99
  • Current list price: $4.99
  • Distinct observed prices: 1
  • Source mode: SteamPulse local tracking

The latest tracked snapshot records ERAIASON at $4.99 in USD, with no active discount metadata. Across the available history SteamPulse has recorded 1 distinct final price in this currency. This supports comparisons with the lowest, highest, and most common values present in the retained record, subject to the stated coverage limits.

The live sales view and Steam sales record provide calendar context for these dates. A date overlap can be compared with a named Steam event, but it does not prove why a publisher changed a price. As new daily rows arrive, this overview recalculates its observed prices, discount windows, and run lengths automatically.
